The hydrophobic tail of the
amphipathic molecule is attracted to oil, while its polar head interacts with water.
其中"hydrophobic tail"指亲油尾部,"polar head"指极性头部。两性分子的亲油尾部被油吸引,而其极性头部则与水相互作用。
The amino acid side chains in a membrane protein often exhibit
amphipathic properties, allowing them to span the lipid bilayer.
这里"amino acid side chains"指的是氨基酸侧链,"membrane protein"是膜蛋白。这句话意思是:膜蛋白中的氨基酸侧链通常具有两性性,使其能够跨越脂质双层。
Amphipathic detergents are effective at breaking down oil-based stains because they have both hydrophilic and hydrophobic components.
"detergents"是洗涤剂,"oil-based stains"指油性污渍。这句话解释了两性洗涤剂为何能有效去除油渍:因为它同时具有亲水和亲油部分。
In the structure of DNA, the phosphate backbone is
amphipathic, which helps stabilize the helical shape.
"DNA structure"指DNA的结构,"phosphate backbone"磷酸骨架。这句话说明DNA的磷酸骨架具有两性,有助于稳定螺旋形状。
The surfactant molecules in soap are
amphipathic, enabling them to lower the surface tension between water and oils.
"surfactant molecules"指表面活性剂分子,"lower the surface tension"降低表面张力。这句话描述了肥皂中两性分子的作用:降低水和油之间的表面张力。
Amphipathic lipids are crucial for the formation of micelles, which are essential for many cellular processes.
"lipids"是脂质,"micelles"是胶束。这句话表示两性脂质对于形成细胞许多过程至关重要的胶束至关重要。
In proteins, the hydrophobic effect drives the
amphipathic alpha-helices to align in the hydrophobic core of a cell membrane.
"alpha-helices"是α螺旋,"hydrophobic core"指疏水核心。这句话解释了蛋白质中两性α螺旋如何在细胞膜的疏水核心中排列。
Amphiphilic polymers are widely used in drug delivery systems, as they can encapsulate both hydrophilic and hydrophobic compounds.
"drug delivery systems"药物传递系统,"encapsulate"包裹。这句话说明两性聚合物常用于药物递送系统,因为它们可以同时包裹亲水和疏水化合物。
The
amphipathic nature of cholesterol in cell membranes contributes to their stability and fluidity.
"cholesterol"胆固醇,"stability"稳定性。这句话指出胆固醇的两性特性对细胞膜的稳定性和流动性有贡献。
Researchers study the behavior of
amphipathic molecules in aqueous solutions to better understand their role in various biological processes.
"aqueous solutions"水溶液,"biological processes"生物过程。这句话说明研究人员研究两性分子在水溶液中的行为,以更好地理解它们在各种生物过程中的作用。
